Wart Removal in Houston: A Dermatologist's Guide to Treatments, Cost, and Whether Insurance Covers It

This article is educational and does not replace an evaluation by a board-certified dermatologist. If you have a growth that is bleeding, changing, or painful, please book a visit.

Most people searching for wart removal want to know two things: how to get rid of the wart, and whether insurance will pay for it. Warts are common, usually harmless, and often go away on their own, but they can be painful, spread, and take months or years to clear. Over-the-counter products work for some people and not for others. Here is what causes warts, which treatments dermatologists use and what the evidence says about them, how cost and coverage generally work, and when a growth that looks like a wart deserves a closer look.

What warts actually are, and why over-the-counter treatment often fails

The HPV types behind common, plantar, and flat warts

Warts are non-cancerous skin growths caused by the human papillomavirus (HPV), and they are contagious until you can no longer see or feel them (AAD). HPV is a large family of viruses. Common warts, plantar warts on the soles, and flat warts are caused by types such as HPV 1, 2, 3, 4, and 10 (Mulhem and Pinelis, 2011). These are different from the types behind genital warts, about 90% of which are caused by HPV types 6 or 11, and different again from the high-risk types linked to cervical and other cancers (CDC). A common wart on your hand is not a sign of a sexually transmitted infection.

Why location changes the approach

The virus lives in the top layer of skin, and the immune system eventually clears most warts. In observational studies, about half of warts resolved within a year and about two-thirds within two years (Mulhem and Pinelis, 2011). Over-the-counter treatments often fail because they are stopped too early, because thick skin on the hands and feet keeps the medicine from reaching the wart, or because the growth is not a wart at all. Location also shapes treatment. Thick plantar warts may need paring first, while warts on the face call for gentler methods that limit scarring and discoloration.

Is wart removal considered cosmetic? What insurance usually covers

Warts are a viral infection

Because warts are caused by a virus and can hurt, bleed, and spread, wart treatment is commonly billed as a medical service rather than a cosmetic one. That said, coverage is set by your plan, not by the diagnosis alone. Your deductible, copay, or coinsurance still applies, and some plans limit coverage when treatment is considered purely cosmetic. Any price you see online is illustrative only; what you actually pay depends on your plan, the number of warts, and the method used. Our post on whether dermatology services are covered by insurance explains the basics.

Common exceptions and prior authorization

Plans differ in how they handle a few situations: many warts treated at once, repeat visits over several months, and treatments such as lasers or injected immunotherapy. Some may require documentation or prior authorization. Before treatment, it is reasonable to ask your plan how wart destruction is covered and whether the method your dermatologist recommends needs approval.

Warts on the face or genital area

Facial warts are still a viral infection, but treatment choices may differ to protect appearance. Genital warts are a separate condition with their own treatment options and should be evaluated by a physician rather than treated with over-the-counter products.

Treatment decisions depend on your individual skin, medical history, and goals. The information below describes how dermatologists evaluate options; it is not a prescription or a recommendation for any specific person.

In-office treatments dermatologists use, and how we choose

Cryotherapy with liquid nitrogen

Freezing the wart with liquid nitrogen is the most familiar office treatment. The AAD notes that most patients need more than one session, that treatment may be repeated every 2 to 4 weeks, and that the area usually heals within 4 to 7 days. A review in American Family Physician found the best results with treatment every two to three weeks and no added benefit beyond three months. The 2012 Cochrane review found that more aggressive freezing worked better than gentle freezing, at the cost of more pain and blistering (Kwok et al., 2012).

Cantharidin

Cantharidin, sometimes called "beetle juice," is painted onto the wart and causes a blister to form underneath it (AAD). The application itself is painless; the blister can be sore for a few days. One cantharidin product was FDA-approved in 2023 for molluscum contagiosum in patients 2 years and older; its use for warts is off-label.

In-office salicylic acid and paring

Paring away the thick top layer of a wart and applying a stronger salicylic acid preparation helps medicine penetrate. The Cochrane review found salicylic acid had the most consistent evidence of benefit among topical treatments, though the effect was modest (Kwok et al., 2012).

Candida antigen and other immunotherapy

For stubborn or multiple warts, a dermatologist may inject a substance such as Candida antigen to prompt the immune system to recognize the virus. In one trial in recalcitrant warts, cure rates were 60% with antigen injections versus 24% in comparison groups; this works only in people whose immune system already reacts to the antigen (Mulhem and Pinelis, 2011). Topical options such as imiquimod work on a similar principle (AAD).

Curettage and electrodesiccation

Scraping the wart away and treating the base with an electric current removes it in one visit for most patients (AAD), but it requires local anesthesia and can leave a scar. It is usually reserved for warts that have not responded to other treatments.

Laser treatment

The AAD notes that a laser can effectively treat stubborn warts, though some patients need more than one session. Pulsed-dye lasers, which target the wart's blood supply, are one type dermatologists use.

Bleomycin for resistant warts

Bleomycin, a chemotherapy medication, is injected directly into stubborn warts, and some patients need more than one treatment (AAD). It is an off-label use reserved for warts that have resisted other options.

Plantar warts and why the sole of the foot is different

Plantar warts grow on the soles and can make walking painful (AAD). Body weight pushes them inward, so a thick callus often covers them, and tiny black dots, which are clotted blood vessels, are a clue they are warts rather than calluses. Paring the overlying skin is usually the first step of any treatment. Houston's warm weather means more time barefoot at pools, gyms, and locker rooms, so flip-flops in shared wet areas are worth the habit.

How many treatments will it take?

Expect more than one visit. Cryotherapy is typically repeated every two to four weeks over a few months, salicylic acid takes weeks of daily use, and immunotherapy injections are spaced several weeks apart. Small, new warts tend to clear faster than large, long-standing, or plantar warts.

At-home treatments worth trying, and ones that are not

Salicylic acid used correctly

Over-the-counter salicylic acid is a reasonable first step for common warts on the hands. The AAD describes applying it once a day after soaking the wart in warm water. Consistency over weeks matters more than strength.

Duct tape occlusion

Covering warts with duct tape became popular after an early positive study, but later trials found no benefit over placebo, and the Cochrane review found no advantage for clear duct tape (Kwok et al., 2012).

Home freezing kits

Over-the-counter freezing kits use a different refrigerant than the liquid nitrogen used in a dermatology office. If one has not worked after a few tries, it is time for an evaluation.

What to avoid

Do not cut, burn, or dig at a wart yourself. It invites infection and scarring and can spread the virus. Apple cider vinegar and other acidic home remedies can irritate or burn the surrounding skin.

When to see a dermatologist in Houston

The AAD recommends seeing a board-certified dermatologist if you have warts on the face or genitals, many warts, a wart that is changing, painful, or bleeding, uncertainty about the diagnosis, no improvement with home treatment, a weakened immune system, or diabetes.

Diabetes and peripheral neuropathy

If you have diabetes, especially with reduced sensation in your feet, do not treat foot warts at home. A minor chemical burn or cut that you cannot feel can become a serious wound.

Immunosuppression

A weakened immune system, from a medical condition or medication, can keep warts from clearing on their own (AAD). In one observational study, 90% of kidney transplant recipients at least five years after transplant had warts (Mulhem and Pinelis, 2011).

Bleeding, painful, or changing growths

Not every rough bump is a wart. The AAD notes that squamous cell carcinoma can appear as a wart-like growth, and that melanoma on the foot can be mistaken for a wart. A growth that bleeds, changes, turns dark, or keeps coming back should be examined. Our skin cancer page explains how we evaluate suspicious spots.

How we approach wart removal at Bayou City Dermatology

Treatment starts with an assessment of the wart, its type, and its location, and in some cases the right answer is to leave it alone. When removal makes sense, we choose a method based on the wart's location and size, your age, how many warts you have, and what you have already tried. Wart care is part of our clinical dermatology services. For children, our post on when to see a pediatric dermatologist may help.

Frequently asked questions

Does wart removal hurt?

Most treatments cause some discomfort. Freezing stings during and shortly after treatment, cantharidin is painless to apply but the blister can be tender, and procedures such as curettage are done with local anesthesia.

How much does wart removal cost in Houston?

It depends on your insurance plan, the number of warts, the method, and how many visits you need. Because warts are a viral infection, treatment is often billed as medical care, but your deductible and copay still apply. Check with your plan before treatment.

Will my HSA or FSA cover wart removal?

Often, yes. The IRS defines medical expenses as costs of diagnosis, treatment, or prevention of disease, and excludes procedures that only improve appearance. Treating a viral infection generally fits the first category, but confirm with your plan administrator.

Can warts come back after treatment?

Yes. Treatment removes the visible wart, but the virus can remain in nearby skin, and new warts can appear. Avoid picking at warts, keep feet dry, and wear sandals in shared showers.

Are warts contagious to my family?

Yes. The AAD notes warts are contagious until you can no longer see or feel them, and they spread to other people and other parts of your own body. Do not share towels, razors, or nail tools, and wash your hands after touching a wart.

Book a wart evaluation

If a wart is painful, spreading, or not responding to home treatment, or if you are not sure it is a wart, book a wart evaluation at Bayou City Dermatology. We will confirm the diagnosis and recommend the treatment that fits the wart and you.
